Question

Do marketing majors at your school study more than, less than, or about the same as marketing majors at other schools? The Washington Post reported the results of the National Survey of Student Engagement that found marketing majors studied an aver-age of 12.1 hours per week. (Data extracted from “Is College Too Easy? As Study Time Falls, Debate Rises,” The Washington Post, May 21, 2012.) Set up a hypothesis test to try to prove that the mean number of hours studied by marketing majors at your school is different from the 12.1-hour-per-week benchmark reported by The Washington Post.

a. State the null and alternative hypothesis.

b. What is a Type I error for your test?

c. What is a Type II error for your test?

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
